Just like roadside assistance from the RAC or AA but a lot cheaper - they've been around for 75 years, but they don't have their own trucks hence aren't anywhere near as visible or well known - but they've won awards for the service so seem very switched on. Special offer at mo add extra drivers for free etc... open till end of jan. They use local recovery companies, who they contact for you. Used this for the first time recenty and all worked like clockwork. you call, they say they'll be there within the hour, send you a text naming the co. that will be picking you up so you know who to expect. Was nice knowing that you end up using a local firm who I guess will get a set fee from GEM.
